Use Formulas in Excel – sums
An Excel tutorial by Peter Kalmstrom
 In
the demo below Peter Kalmstrom goes through the basics of
Excel formulas. The possibility to tell Excel to calculate
is a crucial feature and the most important reason to use
it, and here Peter explains how to tell the program what
to count on = how to create a formula.
When you use a formula Excel calculates with the values
of the cells you have given in thet formula and gives the
result in a separate cell. When the values in the cells
are changed the figure in the result cell will change automatically.
Excel is used for all kinds of calculations – from
personal budgets to very advanced prognoses – but
the calculations cannot be accurate if the formulas are
not correct. With this demo Peter wants to set Excel new beginners
on the right track.
Peter shows:
- What kind of information the cells in an Excel spreadsheet
can contain and how you can see if Excel treats data
as text or numbers.
- How you should NOT use Excel for calculations
- How to calculate a sum using a formula with the
plus sign
- How to calculate a difference using a formula with
the minus sign
- The functions of "sum", parenthesis and colon in
formulas
-
How to use the AutoSum button
Peter uses Excel 2013 for his demo, but the formulas are
the same for earlier versions of Excel.
